Using data from a large longitudinal sample (N = 1,292) of children and their caregivers in predominantly low-income, nonurban communities, we investigated longitudinal relations between attuned caregiving in infancy, joint attention in toddlerhood, and executive functions in early childhood. The results from path analysis demonstrated that attuned caregiving during infancy predicted more joint attention in toddlerhood, which was in turn associated with better executive function performance in early childhood. Joint attention was a stronger predictor of executive functions for lower-income families. Moreover, joint attention mediated the relation between attuned caregiving and executive functions, and this mediation was amplified for lower-income families. These results highlight joint attention as a key mechanism through which attuned caregiving supports the development of executive functions, particularly for low-income families.

共同关注部分调解了低收入儿童的协调照护和执行功能之间的纵向关系。

我们使用来自主要是低收入、非城市社区的儿童及其照顾者的大型纵向样本 (N = 1,292) 的数据，调查了婴儿期的协调照顾、幼儿期的共同注意力和幼儿期的执行功能之间的纵向关系。路径分析的结果表明，婴儿期的协调照顾预示着幼儿期会有更多的共同注意力，这反过来又与儿童早期更好的执行功能表现相关。共同注意力是低收入家庭执行功能的更强预测因素。此外，共同关注在协调照护和执行功能之间的关系中起到了中介作用，这种中介作用在低收入家庭中被放大了。这些结果强调了共同关注是一种关键机制，通过它协调的护理支持执行功能的发展，特别是对于低收入家庭。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
